Printers Furniture.
Patentedlune 9,1874.
N0.l5l,883.
UNITED STATES PATENT GEEIGE.
JAMES A. KEARNEY, OF DETROIT, MICHIGAN.
IMPROVEMENT IN PRINTERS FURNITURE.
Specification forming part of Letters Patent No. 151.883, dated June 9, 1874; application filed April 14, 1874.
To all whom -it may concern:
Be it known that I, J AMEs A. KEARNEY, of
- Detroit, in the county ot' Wayne and State of Michigan, have invented an Adjustable Furniture for Locking Forms on Printing-Presses,
lot' which the following is a specification:
levers as to adjust the bars to varying widths between the side of the chase and the shoulder of the bed, the bars being locked in position to receive and transmit the pressure of the bed-screws.
Figure l is a plan of my device. Fig. 2 is a cross-section at x rv.
In the drawing, A A represent two metal bars, in the inner face of each ot' which is planed a dovetail way, a, in each of which is inserted the dovetail tenons b of two metal blocks, B, sliding freely back and forth, but capable of being locked fast by driving a steel wedge, c, under the shoulder of the tenon. C C are two crossed levers pivoted together at their intersections by a pin, d. The ends of the levers are inserted in grooves in the bases ot' the blocks, to which they are pvoted by pins c. The form is laidon the bed against the shoulder at the back of the bed. The furniture-bars are then placed on the bed, and spread apart until one bar lies against the chase and the other against the clamp at the front of the press-bed, when the two nearest blocks are locked by driving the Wedges under their shoulders. rlhe form is then locked by the pressure transmitted to it by the bars and levers from the clamp-screws, which are screwed up against the outer edge of the nearest furniture-bar. Where a small form is to be locked on a large bed, two of these devices may be used, one in front and the other back ofthe forni.
What I claim as my invention, and desire to secure by Letters Patent, is-
'lhe bars A A, having the blocks B B B B sliding in their dovetail grooves a, with the crossed levers C C pivoted thereto by the pins e, and the Wedges c, constructed and combined as set forth.
